      This sample shows a "fishbone" layout of a tree model of cause-and-effect relationships. This type of layout is often seen
      in root cause analysis, or RCA. The layout is defined in its own file, as <a href="FishboneLayout.ts">FishboneLayout.ts</a>.
      When using FishboneLayout the diagram uses FishboneLink in order to get custom routing for the links.
    </p>
    <p>
      The buttons each set the <a>Diagram.layout</a> within a transaction.
